'err_info' does not support dynamic configuration since it is const type.
Therefore, in order to support new error type later, 'err_info' is changed
to dynamic configuration.

The START_TRANSFER command needs to be executed while in ON/U0 link
state (with an exception during register initialization). Don't use
dwc->link_state to check this since the driver only tracks the link
state when the link state change interrupt is enabled. Check the link
state from DSTS register instead.
Note that often the host already brings the device out of low power
before it sends/requests the next transfer. So, the user won't see any
issue when the device starts transfer then. This issue is more
noticeable in cases when the device delays starting transfer, which can
happen during delayed control status after the host put the device in
low power.

Upon driver unbind usb_free_all_descriptors() function frees all
speed descriptor pointers without setting them to NULL. In case
gadget speed changes (i.e from super speed plus to super speed)
after driver unbind only upto super speed descriptor pointers get
populated. Super speed plus desc still holds the stale (already
freed) pointer. Fix this issue by setting all descriptor pointers
to NULL after freeing them in usb_free_all_descriptors().

"usb: typec: tcpm: Address incorrect values of tcpm psy for pps supply"
introduced a regression for req_out_volt and req_op_curr calculation.
req_out_volt should consider the newly calculated max voltage instead
of previously accepted max voltage by the port partner. Likewise,
req_op_curr should consider the newly calculated max current instead
of previously accepted max current by the port partner.

Userspace has not been allowed to I/O to device that's failed to
be initialized. This patch introduces generic per-namespace character
device to allow userspace to I/O regardless the block device is there or
not.
The chardev naming convention will similar to the existing blkdev naming,
using a ng prefix instead of nvme, i.e.
- /dev/ngXnY
It also supports multipath which means it will not expose chardev for the
hidden namespace blkdevs (e.g., nvmeXcYnZ). If /dev/ngXnY is created for
a ns_head, then I/O request will be routed to a specific controller
selected by the iopolicy of the subsystem.

This patch adds the missing NULL termination to the "bpf" and
"perf_event" object class permission lists.
This missing NULL termination should really only affect the tools
under scripts/selinux, with the most important being genheaders.c,
although in practice this has not been an issue on any of my dev/test
systems. If the problem were to manifest itself it would likely
result in bogus permissions added to the end of the object class;
thankfully with no access control checks using these bogus
permissions and no policies defining these permissions the impact
would likely be limited to some noise about undefined permissions
during policy load.

The commit f1b206cf7c57 ("pinctrl: core: print gpio in pins debugfs file")
enabled GPIO pin number and label in debugfs for pin controller. However,
it limited that feature to the chips where base is positive number. This,
in particular, excluded chips where base is 0 for the historical or backward
compatibility reasons. Refactor the code to include the latter as well.

The generic framework patch broke the current TPM trusted keys because
it doesn't correctly remove the values consumed by the generic parser
before passing them on to the implementation specific parser. Fix
this by having the generic parser return the string minus the consumed
tokens.
Additionally, there may be no tokens left for the implementation
specific parser, so make it handle the NULL case correctly and finally
fix a TPM 1.2 specific check for no keyhandle.

The original patch 8c657a0590de ("KEYS: trusted: Reserve TPM for seal
and unseal operations") was correct on the mailing list:
https://lore.kernel.org/linux-integrity/20210128235621.127925-4-jarkko@kernel.org/
But somehow got rebased so that the tpm_try_get_ops() in
tpm2_seal_trusted() got lost. This causes an imbalanced put of the
TPM ops and causes oopses on TIS based hardware.
This fix puts back the lost tpm_try_get_ops()

Following Race Condition was detected:
<CPU A, t0>: Executing: __netif_receive_skb() ->__netif_receive_skb_core()
-> arp_rcv() -> arp_process().arp_process() calls __neigh_lookup() which
takes a reference on neighbour entry 'n'.
Moves further along, arp_process() and calls neigh_update()->
__neigh_update(). Neighbour entry is unlocked just before a call to
neigh_update_gc_list.
This unlocking paves way for another thread that may take a reference on
the same and mark it dead and remove it from gc_list.
<CPU B, t1> - neigh_flush_dev() is under execution and calls
neigh_mark_dead(n) marking the neighbour entry 'n' as dead. Also n will be
removed from gc_list.
Moves further along neigh_flush_dev() and calls
neigh_cleanup_and_release(n), but since reference count increased in t1,
'n' couldn't be destroyed.
<CPU A, t3>- Code hits neigh_update_gc_list, with neighbour entry
set as dead.
<CPU A, t4> - arp_process() finally calls neigh_release(n), destroying
the neighbour entry and we have a destroyed ntry still part of gc_list.

The bond works in mode 4, and performs down/up operations on the bond
that is normally negotiated. The probability of bond-> slave_arr is NULL
Test commands:
ifconfig bond1 down
ifconfig bond1 up
The conflict occurs in the following process：
__dev_open (CPU A)
--bond_open
--queue_delayed_work(bond->wq,&bond->ad_work,0);
--bond_update_slave_arr
--bond_3ad_get_active_agg_info
ad_work(CPU B)
--bond_3ad_state_machine_handler
--ad_agg_selection_logic
ad_work runs on cpu B. In the function ad_agg_selection_logic, all
agg->is_active will be cleared. Before the new active aggregator is
selected on CPU B, bond_3ad_get_active_agg_info failed on CPU A,
bond->slave_arr will be set to NULL. The best aggregator in
ad_agg_selection_logic has not changed, no need to update slave arr.
The conflict occurred in that ad_agg_selection_logic clears
agg->is_active under mode_lock, but bond_open -> bond_update_slave_arr
is inspecting agg->is_active outside the lock.
Also, bond_update_slave_arr is normal for potential sleep when
allocating memory, so replace the WARN_ON with a call to might_sleep.

pmc_core_lpm_latch_mode_write()
The simple_write_to_buffer() can return success if even a single byte
is copied from user space. In this case it can result in using
uninitalized data if the buf[] array is not fully initialized. Really
we should only succeed if the whole buffer is copied.
Just using copy_from_user() is simpler and more appropriate.

Introduce mt7921_dma_enable and mt7921_dma_disable utilities routine in
order for code reusing between mt7921_dma_reset and mt7921_dma_init.
This is a preliminary patch to reset dma during device driver_own
request.

Move mt7921_dma_reset routine in dma.c and make mt7921_dma_prefetch
static. Moreover add force parameter to mt7921_dma_reset signature.
This is a preliminary patch to reset dma mt7921_mcu_drv_pmctrl.

Currently the assignment of idx dereferences pointer sta before
sta is null checked, leading to a potential null pointer dereference.
Fix this by assigning idx when it is required after the null check on
pointer sta.
Addresses-Coverity: ("Dereference before null check")
